Based on the previous research on the portal crane administration, one standpoint put forward in this paper is idea that is on the foundation of reliability in this paper, two viewpoints take shape when reason is analyzed, that is fatigue break and appearing the flaw that will extend. What is the fatigue break?(this phenomenon is always happen in some place),the fatigue is that board appears apophysis and concave when the board is pressed .so that the board ability of bearing the weight of load will descend. Second , the board appear the flaw that the flaw extends in the some place of board one reason is that the machine works too long, so the board ability of bearing the weight of load will decline.

本论文建立在已有的港口装卸机械管理的研究基础之上，进一步提出了以可靠性为基础的港口装卸机械的管理思想，已有的研究表明，港口机械设备破坏主要由于两个原因，第一是稳定性问题，特别是构件的局部稳定性，所谓稳定性是指：在板的平面内，板受到平行于板面的压力作用，使板发生隆起、内陷等凹凸不平的结果，从而使板受载能力减弱；第二是结构出现疲劳裂纹及其扩展，这是由于设备长时期运行，而造成设备某些部位出现裂纹并得以扩展，使设备承载能力下降。

An experimental equation was acquired between circulating rate and the distribution of the pressure. And the relation between the circulating rate and the opening rate of the valve connecting the returner and the EHE was carefully discussed as well as the relation between the pressure of the EHE and the flow rate of the fluidizing air.

In this paper, two assemblies of special test equipments have been designed and fabricated by authors in our laboratory: namely Catalyst Molding Process Analyzer and Catalyst Mechanical Process Tester. These new skills are developed for the dynamic studies on whole mold forming process and crushing process of Fe-Cr WGHS catalyst pellet. Based on the orthogonal experimental design, the effects of some factors during the forming process of solid catalyst, such as predensification proportion, calcination time, calcination temperature and content of graphite on the mechanical strength of catalyst pellets are systematically examined, and the molding conditions have been optimized. Based on the experimental data, the relationship between catalyst density and forming pressure are educed, and the physical significances of some related parameters are described. The parameter of macro scopic elastic moduls has been suggested to character the mechanical properties of molding catalyst. The effects of molding pressure on mechanical properties of catalyst pellets are discussed, and results show that there exists a optimal molding pressure for the ideal mechanical properties: when over-high or over-low pressure is applied, the specific surface area and side crushing strength of catalyst pellets will decreased. The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.

Compare with tunable filter detection technique, the wavelength measurement technique using tunable source is analyzed theoretically. We design a kind of all-fiber sensing interrogation system, by using long-period fiber grating as edge filter to interrogate the sensing signal of the FBG sensor. The wavelength resolution of the sensing measurement is 0.05nm.A novel FBG Bourdon tube sensor has been constructed, utilizing the pressure mechanic amplify function of Bourdon tube. The measured pressure sensitivity is two orders of magnitude higher than a simple monomode fiber with an in-fiber grating. Especially the pressure sensitivity of the sensor can be determined by changing the parameters of the cantilever beam. Adopting polymer package technique, we coat fiber Bragg grating by using polymer with different mechanic properties.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
